The VForce reed valve system by Moto Tassinari has been the reed valve system of choice by anyone serious about two-stroke engine performance for the last 10+ years. The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design.

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer and they receive less wear than the reed petals on a conventional reed valve design.

Despite having to do some small modifications to install, I love these reeds. Gave my bike lots of low end, crisper response, and keeps me grinning. When matched with proper jetting and exhaust, nobody will be dissapointed.

This item has been great so far on my 2007 rm 125. My only issue is that it has to be cut to size with a hacksaw. The throttle response is much more snappy & crisp.
On another note, I installed one on my son's 2012 rm 85. Be careful as the reed valve system doesn't properly fit snug against the cylinder port. My buddy had this same problem with his son's rm 85. You end up losing air/fuel delivery. I had to use permatex to alleviate the small gap.

Vforce 3 reeds

Great place to order from I received my product in 3 days and I live in Florida I felt the difference immediately I have a more snappier throttle and power band kicks in faster I would definitely recommend this product to anyone!!!! I have been purchasing from Motorsport.com ever since.

I did have to follow the easy instructions to trim the tabs on the stock reed cage for my son's 09 KX85 but no problem. I installed this with stock exhaust and muffler, could definitely hear and feel the difference just from start up and cracking the throttle...crisp. however I added a custom exhaust system before my son rode it so can't really attest to performance gains by itself. Definitely quality product with a cleaner, crisp throttle response...no jetting changes required here in Oklahoma at 2000 ft above sea level. Add this and an exhaust to completely wake up a sluggish powerband.

Great reeds

I personally dont have vforce reeds myself yet but I am going to buy them for my kx85. I recently went over to my friends house and his bike has got these vforce 3 reeds and I rode the bike and they felt great! The bike was awesome! But I have one question. If I bought this product right now does it come with the boot? to hook it up to my carburetor?

Well first the reeds strait out of the box had a big chip in them and then after tearing old power valve out they dont fit in my cr250. Overall they may be great if they were to fit but i returned them and just went to a boysen rad valve.

Increased throttle response and power in minutes!

I have an 04 Yz 125 that was a garage decoration for about 10 years 100% stock original everything low low hours.. Anyways I have to say after torque ing down bolts, new plugs, cleaning a gummed up carb and getting the bike running it just had terrible throttle response no low to mid range control and the high end power band was a slap in the face everytime it's almost too sketchy. After bolting on this reed system (very very easy install) I noticed an immediate crispy throttle and sound, so much smoother I just roll that throttle back and I finally feel like I have total control of this machine, also leaned out my bike which was exactly what it needed to eliminate fouled plugs and splooge. I am 110% satisfied and can't wait to get an exhaust kit and jet kit to really make her rip, thanks Moto Tassinari for helping me build an awesome machine!
